As shown in Figs. 1 to 4 inclusive, the labeling machine comprises asuitable frame I5 on which the operating instrumentalities areconveniently mounted. The latter include means whereby the labels aretransferred from a suitable sourceof lsupply at the label pick-upstation of the machine to the label applying station thereofforapplication to the articles supported' in label receiving positions atthe latter station. For purposes oi' disclosure and description theillustrated mecha--` nism is shown in a form arranged to transfer andapply two labels to the articles, it being understood that this is notvintended to deilnerthe limits of the invention. y 1 In its illustratedform the label transfer and applying means consists of a carriage I6slidably mounted on a horizontal guide rail I'I suitably iixed in placeon the frame I5. The carriage I8 is reciprocated on said rail I'Ibetween the pick-j up and label applying stations of the machine bysuitable mechanism exemplified by the arm I8 which is `pivotally mountedon the frame I5 in any conventional manner. vThe arm I8 is connectedAwith the carriage I6, for instance, by means `ofa yieldingly mounted rodI 9, andis rocked on its pivot in proper timing by conventional meanssuch as shown for instance, in my Patent'No. 2,227,816 of January 7,-1941. The transfer and applying means in the illustrated machine furthercomprises suction controlled means including a plurality of suctionheads corresponding 'in number to the number of labels which are to beapplied to the articles for which said labels are intended. The selectedexample of the novel machine shows two sucticnhead's 20 and 2i carriedin suitably spaced relation by and depending from a suction plate 22connected with a source of;suction in any convenient manner as by meansof a ilexible tube 23. Provision is made in any well-known way forcontrolling the' suction in the heads 20 and 2| and plate 22 in propertiming in an operative cycle of the machine.

The suction plate 22 as `shown in Fig. l is mounted on a yoke or thelike 24, preferably so as -to be readily removable therefrom to permitreplacement and substitutionof plates 22 with varying arrangements ofsuction heads. The yoke or the like '24 forms partof or is carried by amember 25 slidably mounted on the carriage I6 for vertical reciprocationthereon and is arranged to move downwardly relatively to the carriage I8at fthe pick-up station and at the label applying station inrespectivelabel pick-up'and label ap'- plying steps in the well-knownway. Inl the travel' of the carriage I6 from the pickup station tothelabel applying station, that is from right toleft in Fig. 2, the'member25 is suitably maintained at anfelevatlon on lthe carrotatably supportedin the machine and operated in any convenient manner. The roller 21 dipsinto a supply of adhesive vin a container 23 suitably supported on theframe Il, as shown in Fig. 2, and transfers adhesive therefrom to theapplying roller 29 in the well-known way.- Provision may be made in anyconventional manner to prevent the labels from being carried around thecircumferential surface of the applying roller 28 as the coating withadhesive proceeds. During the return movement of the carriage I6 and itsassociated elements from left to right in'Fig .2 or, in other words,back to the pick-up station, the member 25 occupies an elevated positionon said carriage IB in which the suction heads 20 and 2| pass above theadhesive applying roller 26 withtion heads 20 and 2| from becomingcoated and -ing the articles in label receiving position at the labelapplying station, said supporting means being constructed in e. novelmanner to co-operate soiled with adhesive during such return move- A .Atthe label pick-up station the machine is provided with supplies oflabels 29 preferably arranged in the form of stacks in uprightcontainers 30 mounted on the frame i5 in any wellknown way.Suitableprovision is made, for instance, as illustrated in my previouslymentioned Patent No. 2,227,816, for periodically elevating the stacks oflabels 29 to restore the terminal labels at the upperends thereof to apredetermined level. The stacks of labels 29 are located, at the pick-upstation, in registry with the reciprocative paths of the respectivesuction heads 20 and 2|, so as to enable said suction heads 23 and 2| topick-up successive terminal labels 29 therefrom in the well-known way.

To complete the application of the labels to the articles, the machinels provided with pressing means which serves to press the labels intofinal adhesive contact with said articles subsequent to the initialapplication by the suction heads 29 and 2|. As shown in Fig. 1, thepressing means includes a pressure member 3| carried by a plunger 32vertically reciprocable in any convenient manner in a guideway 82*located on the frame i5, in properly timed operative sequence with itsassociated elements. In the specific form shown in Fig. l, two pressuredevices 33 and 34 preferably shaped to conform to the shape of thearticles for which they are designed and preferably made of yieldingmaterial such as rubber or the like, are illustrated. The devices 33 and34 each depend from a carrier 35 slidably mounted on guide pins 36 whichproject downwardly from the member 3| and are provided with cross-pins31 to maintain the carriers 35 thereon. Springs 38 are located betweenthe carriers 35 and the member 3| and serve to yieldingly resist thepressure developing operations of said devices 33 and 34 when thepressure member 3| is actuated. In the preferred arrangement, thepressure member 3| is removably mounted on the plunger 32, for instance,by means of screws 39 to enable various respectively with the suctionheads 20 and 2| or their equivalents, and the pressure devices 33 and34-in automatically setting said articles in the most efcient labelreceiving and pressure receiving position, and to eillciently and safelyeject the labeled articlesfrom the machine.

The aforesaid supporting means in the form shown in Figs. 1 to 4inclusive, includes an intermediate supporting member 40 detachabiymounted in any convenient manner as by means of a screw 4|, upon acarrying member 42. said intermediate supporting member 40 preferablybeing provided on its upper face with a seat defining head 43 made ofsuitable material. The carrying'member 42 in they illustrated example isclamped upon a bracket 44, for instance by means of clamping plates 45removably secured in place in any convenient manner as by means ofscrews 48. The bracket 44 is fixed upon a suitable portion of the frameI5 by one or more bolts 41, or in any other suitable manner, and isfurther provided wlth spaced parallel guideways 48 extending in verticaldirections as shown in Figs. 1 and 2. The article supporting means underdiscussion further includes arms 49 and 49n provided at'their upper endswith seat defining heads 50 and 50|, the latter being mounted on thearms 49 and 49 preferably so as to be adjustable relatively thereto andremovable therefrom as, for instance, by wing nuts 5| and ca -operatingbolts 52. The seat defining heads B9 and s0* co-operate respectivelywith the intermediate head 43 to provide seats which may be referred toas divided seats, in which the articles A and A' are supported in labeland pressure receiving position; in the illustrated example therespective heads 43, 50 and 5|!a are bevelled as indicated at 53 toprovide inwardly converging seats for the accommodation of circular orround articles A andA, such as bottles, cans, and the like. It will ofcourse be understood that the heads 43, 50 and 69* may be shaped toprovide other types of seats depending upon the nature and form of thearticles A and A to be accommodated or supported therein. Preferablysuitable means is provided to properly and accurately position thearticles to be labeled in a recurrent, corresponding label receivingposition. For this purpose the intermediate member A19-may include anupright stop 40 with which the bottom of the article A or A' may beengaged when positioned in the respective seats, as illustrated forinstance in Figs. 1 and 2.

The arms 49 and 49* include preferably integral yokes 54 whereby saidarms 49 and 49a are pivotaily mounted on pivot studs 55 carried bybearing members $9 which form preferably integral partsof and projectfrom the previously mentioned guide members 49, as shown in Fig. l. Inthe preferred arrangement the yokes 54 constitute parts of levers 51 and61n which depend from the arms 49 and 49l respectively, as integralparts thereof and at their lower ends terminate in guideways 58 in whichplates 59 are slidably mounted. The plates 39 include screwthreadedstuds 63 which project through lugs 6| of the levers 51 and 51* for theaccommodation of nuts 82. With this arrangement the plates 59 may2,362,328 'be sudabiy adjusted ln`- the gmdeways sa by screwing the nuts62 relatively to the studs 60 in one direction or the other, as will beapparent. The plates 59 may be fixed in an adjusted position on thelevers 51 and 51 in any convenientmanof the labeling operations.vVlntlfie lllustrated'example, one chute'QI) is provided in receivingrela.'-

-tion to the seat forming head 50 of the arm 49 and the seat forminghead 430i the intermediate ner as by means of screws 63 extendingthrough slots 64 into threaded engagement with the levers 51 and51.respectively. The arms 49 and 49 are yieldinglyv connected with eachother by means of a spring 65v having its opposite ends connected withapertured ears 66 formed on said arms as shown in Fig. 1 and exerting atension tending to pivotally swing said arms 49 and. 49

in directions to shift the seat defining heads 50 or 50 inwardly towardthe seaty defining inter' -further include preferably integral members69 and 69 which extend inwardly toward each other and at their opposedinner end are provided with transverse sections formed with lengthwiseextending guide grooves 1I in which bearing boxes 12 are slidablymounted and xed in adjusted positions by means of screws 13 which aremovable in slots 13 provided in thetransverse sections 10 for'thlspurpose as shown in Fig. 2. Rollers 14 and 14 are rotatably mounted onthe bearing boxes 12v and arel normally arranged to cooperate with theupper wedging or camming end 15 of a Acontrolling member 16 slidablyVmounted inthe guide members 48 for vertical vreciprocation therein,said controlling member ner to develop a tension tending to move said.

slide 16 and locking member 11 downwardly relatively to the guidemembers 48. Any .suitable means may be provided for vverticallyreciprocats ing the control member 16 and the locking member 1.1 toeffect the desired results to be more fully described further on in thespecification. For instance, as shown in Figs..1 and 2, a bell-cranklever 19 may have the free end of its one member rounded as illustratedat 80 and located in `a slot 8| with which the-control member 16 isprovided, as shown in Fig. l. The bell-crank lever 19 is pivoted at 82for instance upon a portion of the bracket 44 and has itsother arm,which is of considerable width, provided witha slide 93 adjustablymounted on said member. of the bell-crank lever 19 by means of screws 84and a slot 85.v A roller 86 is rotatably mountedupon a downwardlyprojecting lug 83 ofthe slide 83 so that said roller 86 partakes of themovements of adjustment of said slide. The roller 86 is in rollingengagement with a cam 81 carried by a shaft 88 suitably mounted in themachine and rotatively operated in any convenient manner, a spring 89effective on the first-mentioned arm or member of the bell-crank lever19 developing a tension thereonl whereby the'roller 86 is maintained inloperative contact with said cam 81.

member 40. This chute 90v may be supported in any convenient manner andas shownV is provided with a supporting bracket 9I which is adjustablyclamped in place by means ofva screw 92 on the extension of the lowerclamping plateV 45, as illus-` trated in Figs. 1 and 2. v

In the operation of the machine the carriage I6 is reciprocated on thehorizontal guide rail I1v by means oi the arm I8 and the connecting rodI9 and the associatedA mechanism between the label pick-up station andthe label-applying sta tion of the machine. At the label pickup station,the member 25 is moved downwardly on the carriage I6 in the conventional`manner to bring the suction headsl 20 and -2I into engagement with theterminal labels 29 at the upper ends lof the supply stacks in therespective containers 30. At the proper moment, suction is developed inthe suction heads 20 and-2| and the latter are lifted upwardly byraising the member 25 on f' the carriage4 I6 to carry said terminallabels -29 upwardly away .from the respective supply stacks. Thecarriage I 6 is then shifted to kthe left in Fig. 2 along the guide railto cause the labels 29 carried by the suction heads 20 and-2| to pass intangential adhesive receiving relation to the adhesive applying roll 26to receive coatings of adhesive therefrom in the well-knownl way. Themovement of the carriage I8 to the left is continued until the applying-station oi the machine is reached at which time the member 25 is againmoved downwardly on the carriage II6 to correspondingly move the'suction heads 20 and 2| downwardly and to thereby bring the labels 29carriedy by said suction heads into label applying relation to thearticles mounted on the previously described supporting means. Y

LIn the illustrated example shown in Fig. 1, separate labels may beappliedsuccessively to the of the labeling operation a single article FAmay be located in the seat provided by thel intermediate head 43 and thehead 50' of Fig. 1 with the opposed seat between theintermediatehead 43and the head 50 empty. InV this event the previously described downwardoperation of the suction heads 20 and 2I will initially 4apply a label29 to the article A with the label carried by the suction head 2I beingwasted and discarded. Alternatively, articles A and A' may becoincidentally positioned in both seats, or in other words, supportedupon both arms 49 and 49l and the `intermediate member 40 as shown inFig. l. Under such conditions, the downward movement of the suctionheads 20 and Q2| will coincidentally initially apply different labels toboth articles A and A. In either case, after the initial application ofthe label orA labels has taken place, the slide 25 will be movedupwardlyon the carriage I6 to raise the suction heads 2Q and 2| awayfrom the articles A and A'frespectively, to a level above that of theadhesive applying roller 26. The carriage I8 will then again be moved tothe right on the guiderail I1 to bringlthesuction heads 20 and 2l aboveand in registry withthe respective supply stacks of labels ready for arepetition of the pick-up operations vwhereby-the nextsuccessiveterminallabels 29 are picked up from said supply stacks. In themeantime, in. proper operative synchronism with these opera-` tions eplungerv $2 is moved downwardly in the gui eway 32e in any conventionalmanner to correspondingly move the pressure member Il downwardly tothereby bring the pressure devices 'I3 ,and 34 into yielding contactwith the initially applied labels on the articles A and A to develop apressure thereon whereby the application o! the labels to said articlesis completed. Ii as previously mentioned, only the article A is in labelreceiving position, at the beginning of an operative period, thepressure device I4 in such case will develop no operative enect. Withonly the article A initially in position for labeling, this article Asubsequent to the application of a label thereto, is transferred in areverse position to the seat between the heads 43 and Bil* and becomesthe article A. It, on the other hand, articles A and A arecoincidentally in place in the respective seats, the article A' istransferred in a reverse position to the seat previously occupied by thearticle A and the article A is transferred in a correspondingly reverseposition to the seat previously occupied by the article A', whereuponthe previously described initial application of labels and subsequentpressure thereof 'on said articles is repeated. These operative stepsmay be continued in repeated sequence. throughout a given operativeperiod or the machine. In theA preferred operation the seat between theheads 43 and ill* is without an article at the beginning oi theoperative cycle and the article A after the first label has been appliedthereto as described, is'transferred in a reverse position in which thearticle A' is illustrated in Fig. 1, and a successive article Av isplaced in the seat between the heads 43 and 50.

In such case when the next successive label applying steps have beencompleted to provide the article A' with its second label, thecompletely labeled article A' is ejected into the chute 9U and removedfrom the machine.

In this connection it is to be noted, with the machine set up for use asillustrated in Fig. l, that the one' roller 14 is adjusted to aninoperative position on the transverse section oi the member 65 of thearm 49 so as to lie outside of the path of the vertically moving controlmember 1li. Under such conditions as the cam 81 is rotated during anoperative period of the machine, .it will act on the roller 88 tothereby swing the bell-crank lever 19 in a direction to raise thecontrolling member 1S in the guides 48. The wedging or camming end ofsaid member 1B will thus act on the roller 14a and by exertinga cammingaction to the left thereon laway from the head 43. In other words, the

heads l0 and Eli* are firmly fixed against any movement away from thehead 4I under the camming forces developed by the articles A and A onlthe respective seats during the labeling operations.

As previously stated, it is preferred to apply a label to the article Aand to then transfer said article A in reverse position to the seatpreviously occupied by the article A', for receiving a second label sothat the labels are successively applied to a given article in diametricopposite positions or other relation thereon. Ii labels are appliedcoincidentally to articles A and A first in one position and then in areverse position in the respective seats, it may be desirable to ejectthe two completely labeled articles A and A' from the machinesimultaneously. In such case, the roller 14 is adjusted to an operativeposition on the section l0 oi the extension 69 oi.' the arm 49 into thepath of the wedglng or cammlng end 15 oi the controlling member 1B.Under such conditions. when the latter is vertically moved as previouslydescribed, both arms 49 and 48* will be pivotally actuated tovcoincidentally shift the heads 50 and 50 away from the head 43A tothereby permit both completely labeled articles A and A' to be ejectedfrom the machine. It will of course be understood that in such case awill pivotally swing the arm 4Sla correspondingly to the left'to movethe head 50" away from the head 43 a distance sufiicient to permit thefully labeled article A todrop downwardly into the chute 80; in otherwords, the completely labeled article A' is dislodged from itssupporting seat.

As the controlling member 16 is thus raised, the

locking plate 11 will be correspondingly lifted out or registry with theplates 5B so as not to interi'ere with the above described pivotalmovement of the arm 49a. lBecause of the inoperative position of theroller 14 out of the path of the controlling member 16, the upwardactuation of the latter will have no effect on the arm 49 so that thearticle A will remain in position in the seat between the heads Bil and43. -As the cam 81 continues its rotation, the spring 88 will cause thebell-crank lever 19 to be pivotally moved in a reverse direction wherebythe control member 1i is moved downwardly in the guides 48 tothereduplicate chute 90 will be located in receiving relation to theheads 50 and 43. As the controlling member 16 moves downwardly in themanner previously set forth, both arms 49 and 49a will be pivotallyactuated to restore both heads i0 and B* into proper operative relationto the head 43 to provide the respective seats for successive articles Aand A. The inward pivotal movements of the arms 49 and 49 eitherindividually or simultaneously will be arrested by the stops 61 so thattheheads 50 and 50a will be properly positioned relatively to the head43 to properly support the articles to be labeled in a most etlicientmanner. Ihe degree of reciprocation of the controlling member 16 and itsassociated parts may be varied by adjusting the slide 83 and roller 8Bon the depending arm of the bell-crank lever 19 as will be apparent.

In some instances, it may be desirable to render the arms 48 and 49lwith their associated parts and associated mechanism temporarilyinactive or inoperative for the purpose, for instance,

of substituting a central supporting member of different type for thesupporting member 40. Such an arrangement is illustrated in Fig. 5 inwhich the supporting member 4l)b is provided with seats 53 for theaccommodation of articles a and a' arranged to be coincidentally labeledby means of suitable mechanism as illustrated in Fis. 5. I

To eiect the inoperative setting of the arms li8 and 49a and theassociated mechanisms the i 2,882,828 is disconnected from the arms49and 49and the latter are swung to the inactive and inopera tivepositions illustrated in Fig. 5, it being understood that thecontrolling member 18 and locking plate 'l1 are Iraised in the guideways48 to enable this to be done. The support 40b may be replaced by thesupport 40 at will and the otherparts of the mechanisms restored tooperative condition at any time desired by again connecting the spring65 with the arms 49, 49 and by adjusting the roller 88 into properoperative relation to the cam 81.

In the form shown in Figs. 6 and "I, the mechanism generally correspondsto that of the form shown in Figs. 1 to 5v inclusive. It will be notedhowever as illustrated in Fig. 6 that the arrangement under discussionis designed for applying labels to articles of substantially rectangularform. It is to be understood however that this is in no sense to beconstrued as a limitation as the mechanism 'of Figs. 6 and '7 may beused with equal eiilciency for supporting articles of circular and otherconfiguration, in label receiving positions. In the illustrated specificconstruction, the seat forming heads 43, 50 and 50a are replaced by anintermediate seat forming head 43P- located upon the intermediatesupporting member 40 and by the seat forming heads 50b and 50 removablysecured by means of the wingenuts Iiiv and co-operating bolts 52 uponthe upper ends of the respective arms 49 and 49B. The heads 43, 5 0" and50 include angular \re cesses 53a normally located in associated rela,-tion to provide angular seats for the accommui,` dation of theapproximately rectangular articles A3 and A3; this relative positioningof the parts is effected by the stops 81 in co-operation with the arms49 and 49B. In the illustrated preferred arrangement the intermediatehead 43a is yieldingly mounted on the vintermediate supporting member 40by means of springs 92 and guide pins 93 which project downwardly fromthe head 43 through apertures provided for this purpose in theintermediate supporting member 40 as ,shown in Fig. 6. The guide pins 93are provided with stop pins 94`which by engagement with the supportingmember 40 maintain the head 43a in operative connection with thesupporting mem, ber 40.

In the form now beinglescribed the articles A2 and A3, after' theapplication of the labels has been completed. are dislodged from thesup-4 porting seat or seats and dropped upon a table 95. the upper faceof which preferably carries a pad 96 of cushioning material, such asrubber, or the like, to neutralize the impact Iof tbe dislodged articlesA3'and A3 and prevent breakage thereof or otherinjury thereto. In theillustrated example the table 95 and its cushion 98 are locatedbeneathand inreceiving relation to the seat formed by the head 5|)bkofthe arm 49 cent receiving'relation to the cushion l89 of the table95, as shown in Fig. '1. The aforesaid conveyer 99 serves to transferthe labeled articles from the labeling station subsequent to theapplication of the labels to a convenient point out- 'side of themachine for suitable disposition as may be desired. For the purpose oftransferring the labeled articles from the cushion 98 oi the table 95 tothe conveyer 99 the machine may be provided with a suitable meanswhereby this is accomplished. As shown in Fig. 7, this means vcomprisesan impelling member |00 movable and the seat forming head 43*l of theintermediate member 40 as illustrated in Fig. 6. Obviously the table 95and its cushion 96 may be correspondingly located in receiving relationto the seat forming head|i0c of the arm 49l and the intermediate seatforming head 43a. In any case, the table 95 and its-cushion 96 'aresupported in -the machine in any convenient manner as by means of abracket'91 secured upon the bracket 44 for instance by means of screwsl98. The arrangement being described further includes a travellingconveyer 99 operated in any suitable manner and having its upperrun'suitably supported against sagging and travelling inadjatransversely 'of the cushion 98 in operative relation thereto andlocated at the upper end of one arm of a bell-crank lever |0l. Thelatter is pivotally mounted at |02 upon a lug or lugs |03 which may besecured to or form part of the bracket 44. The arm |0| in the operationof the mechanism is rocked upon its pivot |02 in a manner to cause theimpelling member |00 to shift the labeled articles transversely of thecushion 96 of the table 95 and to transfer said articles to the conveyer99. Any suitable mechanism may' be provided for this purpose. Forinstance, as shown in Fig. '1, the other arm of the bell-crank lever |0|may be pivotally connected with a link |04 which in turn ispivotallyconnected with an operating lever |05 pivoted at |08 in any conventionalmanner upon the frame l5 of the machine andcarrying a roller |01arranged in rolling engagement with a cam |08 xed upon the previouslymentioned shaft 88. A spring |09 has its one end connected with a lug||0 of the rst mentioned arm oi' the bell-crank lever I0| and its otherend secured to a pinsuitably located on the iframe I5. 'I'his spring.|09 serves to return the bell-crank lever |0| 'to the normal positionillustrated in Fig. '1 and at the same time to maintain the -roller |01vin rolling engagement with the cam |08. p

With the arrangement shown in Fig. 6 it may be assumed that the roller14 of the arm 49 occupies an inoperative position out of the path oireciprocation of the controlling member 18. Under such conditions whenthe labels have been applied to the article A3 the arm 49 will bepivotally'actuated to shift the seat forming head 50D away from the seatforming head 43 to thereby dislodge the labeled article A3 from saidsupporting seat and permit said' labeled article A3 to 'drop to and uponthe cushion 9 8 of the table 95.

'to the cushion 98 without material change in position and with thebottoms of said articles A3 substantially in registry .with andproximity to theimpelling member |00.

As the operation of the machine continues, the

cam |08 in proper operative synchronism with the other operative stepswill act on the roller |01 to pivotally raise the lever |05 and therebydevelop an upward pushing force on the link |04 which causes thebell-crank lever |0| to be plvotally actuated in a direction to shiftthe impelling member transversely across the cushion 96 toward the leftin Fig. '7. It will be understood that the table and cushion 98 are bothslotted in registry with each. other and with the bellcrank lever |0|topermit this transverse movement of the impelling member |00. As thelatter is thus actuated it will be develop an impelling4v force on thecompletely labeled, article A3 which is in position on the cushion 98and thereby will force said article As from said cushion 88 and transfersaid labeled article As to the conveyor 99. The labeled article As thustransferred is carried from the machine to a suitable point oi disposal.When this transfernof the completely labeled article A3 to the conveyer88 has been completed, the continued operation of the cam |08 willpermit the spring |08 to restore the bell-.

` cludes supplies of labels 29 preferably arranged in the form o! stacksin upright containers 30 in the same way as shown and described withrespect to the form of the invention rst referred to herein. The machineunder discussion also includes adhesive applying means which may be ofthe same type and located in the same way as shown in Fig. 2. Themechanism whereby successive labels are removed from 'the supply stacksat the pick-up station and transferred to the label applying station mayalso be of the same general construction as that shown in Figs. l and2', and previously described herein with re.. spect thereto. During thetransmission of the successive labels from the pick-up station to thelabel applying station, said labels receive a coating of adhesive in thesame manner as previously mentioned herein. 4

The label transfer and applying means in the form of the machine nowbeing describedalso includes a suction plate 22" provided with twosuction heads and 2l depending from the suction plate 22* which. as inthe form first described, is mounted on the yoke or the like 2i,preferably so as to be readily removable therefrom to permit replacementand substitution of plates 22* with varying arrangements of suction fheads.

As in the form first described, the instant fornix of the machineincludes pressing means which 'serves to press the labels into finaladhesive conu tact with the articles subsequent 'to the initialapplication of said labels thereto by the suction heads 2|! and 2 I. Asshown in Fig. 8, this pressing means includes supporting brackets 35*which depend from and are carried by a pressure member illacorresponding to the pressure member 3| of Fig. land correspondinglymounted and operated. Two pressure devices each consisting ofco-operatlng pressure levers 33* and 34* are pivotally mounted at ||2upon the respective supporting brackets 35 as shown in Fig. 8. Thepressure levers 33 and 3ia in the illustrated example are curved to ntthe articles being labeled and preferably are provided withcorrespondingly curved pads H3 oi' resilient material. The levers 33sand 34 of each pair are resiliently controlled by means of springs |14and are maintained in their normal position by said springs inco-operation with stops lli located on the brackets 35a as shown in Fig.8.

The means whereby the articles Al and A5 which as previously statedherein may be exempliied bythe conventional electric fuses, aresupported in label receiving positions at the label applying station inproper operative relation to the respective suction heads 20* and 2|*and the lit) . aseasae respective pressure devices 33' and Il includesan intermediate supportin member 40* which is provided at its uppersurface with heads m and 43 for defining seats conforming to thearticles being labeled. As shown in Fig. 10 the heads 43h are located inopposed spaced relation to each other on the supporting member 4|!Ilwhile the head 1l3 comprises a continuous unit located in spacedparallel relation to the heads has iilustrated in Fig. i0. Thesupporting member do is preferably yieldingly supported upon a carryingmember 42* by means of a bolt 84' and a spring 92* as shown'in Fig. 1l.The carrying member 42e may otherwise correspond to Vthe carrying memberl2 of the form rst described and be correspondingly supported in themachine. The

seat defining heads Il and 43 in the illustrated example are bevelled asindicated at 53h for the purpose of defining the aforesaid seats as willappear more fully hereinafter. Co-operating seat defining heads d and 50are preferably U- shaped as shown in Fig. 10 with the parallel legs ofsaid heads l0* provided with bevels 53 normally located in co-operativerelation to the bevels 53h and co-operating therewith to provide seatsin which the articles A and A5 are supported. The heads 50d and 50 arecarried by members or plates 8 removably secured in place by means ofscrews H1 upon the upper ends of arms 49 and 8 which correspond to thearms I0 and lill oi the forms previously described and are similarlyarrested in their normal positions by adjustable stops $1. The arms 49hand v49 are pivotally mounted at I6* upon lugs 58" secured to or formingpart of a guide bearing 43* suitably supported on the frame I5 oi' themachine in any convenient manner, iorinstance, in the same way as theguideways I8 are mounted in the forms of the machine previouslydescribed herein. s The arms I8 and Se include extensions "which projecttoward each other and are pivotally connected at IIB with links ||9which in turn are pivotally connected at |20 with a controlling member16* upon opposite sides thereof as illustrated in Fig. 8. Thecontrolling member 'IB is slidably mounted for vertical reciproca tionin the guide bearing il* and at its lower end is provided with apreferably adjustable projection shown in the form o! headed screw |2|fixed in an adjusted position by a lock nut |22. The guide bearing I8*is provided with a slot |23 for the slldable accommodation of a pin |24projecting from the controlling member 16* and serving to receive oneend of a spring |25 the other end oi' which is attached to a pin |28projecting from the guide bearing las as illustrated in Fig.' s.

Any suitable means may be provided for vertically reciprocating thecontrolling member 18 in the guide bearing I8* in proper synchronsm-with the associated elements of the machine.

For instance, as shown in Fig. 9, the headed screw I2! -may rest inengagement with a roller Bil'A carried by one member of a bell-cranklever I8s which is pivoted at 82* upon a bracket 82h suitably mounted inthe machine, as illustrated in Fig. 9. The other arm of the bell-cranklever 19 is provided with a roller 86'i located and maintained inrolling engagement with a cam 818 iixed upon a shaft 88 convenientlymounted in the machine and operated in any suitable manner.

In addition to the parts so far described, the machine under discussionincludes deiiecting means whereby articles of dinerent type asexintended manner.`

- |49 withone aseasas empliiied by electrically perfect and electricallyimperfect articles are separately ejected from ythe machine. In theillustrated example electrically defective fuses A4 and A5 are ejectedfrom the machine and discarded, while the electrically perfect fuses A4or A5 are separately ejected from with a wire |52 leading to said sourceof electricity to complete the circuit. The switch |50 `is of a typewhich is normally open to break the aforesaid electric circuitand islocated and supl ported-in the machine inv any'suitable mannerin .thepath of-*the carriage i8 and so as vto be adjusted to its closedposition to closethe aforesaid electric circuit when it is engaged bysaid carriage I6 as the latter reaches its terminal position at thelefthand end of the guide rails |1. as shown in Fig. 9. It willbe'understood that the intermediate supporting member |405 on arepivotally connected at .|29 with members |30 l and |30 respectively,said members |30 and Illil'L being slidably -connected at their lowerends with bell-crank levers |3| and |3I. The members |30 and |30 areeach provided with abutments preferably in the form of adjustable nuts-'|32 against which springs |33 abut with 'their one end, the other endsof said springs being in engagement with the levers |3| and |3|5respectively. The bell-crank levers |3| and |3|5 are mounted for rockingmovements on the pivots 82n and are provided with rollers 80b in rollingengagement with the cam 80 suitably mounted on the shaft 885. Springs89* are provided for maintaining the rollers 805 in contact with the cam80 as shown in Fig. 9.` The members |30 and |305 are further providedwith nuts |34 vwhich by engagement with the bell-crank levers |3| and|3|a arrest the movements of the membersl Iiili andv lfrelatively tosaid bell-crank levers |3| Y and |3l under-the iniiuence of the springs|33.-

The deecting bell-crank levers |21 and |215 are further provided withpins arranged to be engaged by latch members |38 and |38*L respecrtively, to thereby lock said levers 21 and |215k which the heads v43band. 43c are located is preferably made of insulation or other suitableelectrically non-conductive material. Similarly the heads lilid and Bil"mayalso be made of electricallynon-conductive material such as asuitable insulation substance.

In the normal condition of the machine at the beginning oi' an operativecycle the parts may occupy the positions illustrated in Fig. 8 inwhichthe articles A4 and A5, hereinafter referred to as fuses, are located inlabel receiving position and in operative relation to the suction heads20ai and 2|a and the pressing devices 335 and 34B. The

labels are initially applied. to the fuses A4 and A5 by the suctionheads -20ahd 2|a respectively, and

pressed into nal adhesive connectionwith said fuses A4 and A5 bythepressure devices 33 and f| to its closed position to Athereby connectthe wires |49 and |5| witheach'other and with the wire |52 which leadsto a source of electric power. When the fuses A4 and 'A5`are in positionin the respective seats formed'by the bevels 535 and 53, the metallicends of said fuses will connect the Y heads 435 with the head`43` sothat the electric circuits which includesth'e electro-magnetic coils |4|and |4 |a will be completed through the fusable wires or theirequivalentwhich constitute parts of said fuses A4 and A5 intheconventional manner. If the fuses are electrically perfect, the electriccurrent will pass therethrough andwill enerwhich may-be fixed upon saidshafts 31 in any j convenient manner. The arms |38 are connected bymeans of links |39 with the armatures |40' and'l40a of electro-magneticcoils |4| and |41il located respectively uponopposite sides Aof theframe l5 and suitably'mcunted in place asxby meansk of supportingbrackets |42, asshown in.

Fig. 8. A

'I'he--deiiecting means now being described includes electric circuitswhereby the electro-magjnetic coils |4| and |4I* are automaticallycontrolled in a manner to bring about the automatic discarding ofdefective articles A4 and A5@ in the ilning heads 435 and 43'? vare madeof metal `or any other suitable electrically conductivefmateand |45 asillustrated in Fig. l0. A wire |46 leads from the binding screw |43 toone side of :the electro-magnetic coil I4| while a corresponding wire |46* leads from the binding screw |44 to one side of the electro-magneticcoil 4|. The

`Opposite sidesfof the coils |4| and |4| are conh nected by means of awire |41 with a wire .|48

For thispurpose-the seat dev |21* for pivotal operation' as-will appearmore 55V out of engagement-withV the ca operating pins |35 to therebyrelease thebell'fcrank levers |21 and fully hereinafter. In "this.position of the parts las the bell-crank lever- 19# is actuated by thecam j 81'i to operate the-controllingmember 165 in a manner to swingthearms '49,5 and 49 in directions away from each other. y the heads 50dand rial-and are provided with binding screws las, |44 3' lease thebell-crank levers"'|21.a nd |21.

50 will be moved a`way from the `heads 43h, 43". to thereby dislodge thelfuses A4-andA5 from the respective supporting seatsk It said fuses A4.and

A5 are electrically perfect, the electrical current will passtherethrough tothe Velectro-magnetic coils |4| and 4 la and willvelectrically energizey the same. As a result the armatures |40 and |40lwill be operated tozshift thelatch members |38 and |36 to inoperativepositions and .thereby're- The latter accordingly will be pivotallyoperated to reverse the position of the chutes 90'and 305 relaf tivelyto the respective fuse supporting seats; in

other words, the chutes 905 will .therebybe moved into registrywith-'theg 'respective. seats in which operations. 'I'he labeled fusesA* and A which are electrically perfect will thus drop into the chutes90b and will be ejected from the machine for such disposition as may bedesired.

On the other hand, if for instance one oi the fuses, say the fuse A* iselectrically defective, the electrica] current will not passthrough'ithis defective fuse when the switch |50 is closed and theelectro-magnetic coil lli consequently will not be electricallyenergized. As a result the amature |48 will not be elevated and thelatch member ISI will remaininengagement with the pin |35 to therebyretain the chute 90 of the bell-crank lever |21 in position in registrywith the seat in which the defective fuse A* is supported. As the arms491 and 49" are operated in the manner pretralized by the spring |33 andbecause of the slidable yielding connection or said member |30 with saidbell-crank lever |3i. If both fuses A4 and A are electrically detective,both chutes 80 will remain in place for the reception of said defectivefuses A4and A.

From the abovedt will be apparent that in addition to providing for theemcient application of labels to electrical articles such as electricalfuses.

this form of the mechanism in addition automatically separates imperfectelectrical articles from the perfect ones. y

The electrical arrangement described in connection with the form of themechanism shown in Figs. 8 to 11 inclusive, may if desired be combinedwith the other forms of said mechanism herein illustrated and described.

The novel mechanism in all of its forms provides for the efficientapplication of labels to the articles in the manner set forth and may beincorporated without difiiculty in existing labeling machines.

Various changes in the specific forms shown and described may be madewithin the scope of the claims without departing from the spirit oi' theinvention.
